  [HIP] emit macro `__HIP_NO_IMAGE_SUPPORT`

HIP texture/image support is optional as some devices
do not have image instructions. A macro __HIP_NO_IMAGE_SUPPORT
is defined for device not supporting images (https://github.com/ROCm-Developer-Tools/HIP/blob/d0448aa4c4dd0f4b29ccf6a663b7f5ad9f5183e0/docs/reference/kernel_language.md?plain=1#L426 )

Currently the macro is defined by HIP header based on predefined macros
for GPU, e.g __gfx*__ , which is error prone. This patch let clang
emit the predefined macro.
